CIM quiz

A CIM motor is attached to a small dynamometer which exerts a fixed constant load torque of 100 oz-in on the motor shaft. The CIM is directly attached to a 12VDC source (assume no internal resistance) with heavy gauge wire and connectors (assume no resistance). Assume the CIM's specs are exactly as specified in the attached screenshot.

Questions:

1) What is the CIM's speed?

2) What is the CIM's current?

3) How much power (watts) is being input to the CIM?

4) How much power (watts) is the CIM delivering into the load (dynamometer)?

5) How do you account for the difference between #4 and #3 above?
